Abstract

Purpose

The purpose of this paper is to find an efficient fabric defect detection algorithm by means of exploring the sparsity characteristics of main local binary pattern (MLBP) extracted from the original fabric texture.

Design/methodology/approach

In the proposed algorithm, original LBP features are extracted from the fabric texture to be detected, and MLBP are selected by occurrence probability. Second, a dictionary is established with MLBP atoms which can sparsely represent all the LBP. Then, the value of the gray-scale difference between gray level of neighborhood pixels and the central pixel, and the mean of the difference which has the same MLBP feature are calculated. And then, the defect-contained image is reconstructed as normal texture image. Finally, the residual is calculated between reconstructed and original images, and a simple threshold segmentation method can divide the residual image, and the defective region is detected.

Findings

The experiment result shows that the fabric texture can be more efficiently reconstructed, and the proposed method achieves better defect detection performance. Moreover, it offers empirical insights about how to exploit the sparsity of one certain feature, e.g. LBP.

Research limitations/implications

Because of the selected research approach, the results may lack generalizability in chambray. Therefore, researchers are encouraged to test the proposed propositions further.

Originality/value

In this paper, a novel fabric defect detection method which extracts the sparsity of MLBP features is proposed.

Abstract

Purpose

To improve humanized management of Chinese teachers, the aim of this study is to, first, investigate the stress of Chinese teachers, and, second, to examine the relationship of teacher stress with coping strategies and social support. Moreover, an attempt is made to examine the moderating role of coping strategies in the relationship between social support and teacher stress.

Design/methodology/approach

Participants consisted of 363 teachers from 6 public primary and secondary schools (both regular and vocational schools), who completed 3 self-report questionnaires examining teacher stress, coping strategies and social support. The methodology used was t-test, correlation analysis and hierarchical multiple regression analysis.

Findings

There are more than 50 per cent of primary and secondary school teachers suffering from mild to extremely severe stress. Working environment (regular or vocational schools), gender and age affect teacher stress. Social support and passive strategies have significant relationships with teacher stress, and passive strategies moderate the relationship between social support and teacher stress.

Research limitations/implications

The study is based on a sample taken from public primary and secondary schools, and the character of the research was cross-sectional. Therefore, we must be cautious in generalizing the findings. An important implication for management of the findings of this study is the importance of humanized management for teachers. To reduce teacher stress, more social support should be provided by educational administrators, and teachers should be trained to avoid using passive strategies.

Originality/value

Through the investigation into the teacher stress in both regular and vocational schools, this study provides a new point of view for human resource managers to control and reduce teacher stress in China by improved humanized management.

Abstract

Purpose

This study aims to decrypt the efforts made by Chinese people's courts nationwide to protect the rights of Chinese posted workers in the Belt & Road (B&R) countries by investigating labour litigation cases with an extraterritorial application of Chinese labour law (under the “doctrine of overriding mandatory labour rules”).

Design/methodology/approach

This study collected all labour litigation from 2014 to 2018 brought forward by Chinese posted workers in Chinese courts against Chinese enterprises regarding the performance of employment contracts in the B&R countries where Chinese labour laws were mandatorily applied under the doctrine of overriding mandatory labour rules. The study adopted a qualitive research approach to analyse the compiled cases to explore their characteristics and effects.

Findings

This study found that the volume of labour disputes in the B&R countries had a somewhat positive correlation to the amount of investment from China. However, this correlation was rather superficial when compared with the correlation to the type of industrial sector (e.g. the construction sector) and to the claim category (e.g. remuneration claims). Moreover, labour disputes in both the B&R countries and China shared a great deal of similarity with regard to their concentration in certain sectors and in certain types of claims. Therefore, mandatorily applying Chinese labour law could be convenient for Chinese workers returning from abroad who seek remedies and could allow Chinese judges to issue affirmative decisions regardless of the territory in which the worker was posted.

Research limitations/implications

The cases collected by this study were limited to those filed in China by Chinese workers who were hired by Chinese enterprises and sent to work in the B&R countries and did not include those filed in the B&R countries by Chinese posted workers. Future research should therefore attempt to gather a broader range of labour disputes to further clarify the issues and need for labour protection for Chinese posted workers in the B&R countries.

Practical implications

This study argues that the doctrine of overriding mandatory labour rules is not entirely unproblematic because it might arbitrarily rule out the standards set by foreign labour legislation that could be more favourable to workers or offer them greater protection. Therefore, giving judges a certain degree of discretion is imperative to allow them to apply foreign labour standards when they have been proven to benefit workers.

Originality/value

Apart from a handful of reports on individual cases, there have been very few empirical studies regarding the general picture of labour protection for Chinese posted workers in the B&R countries. This study has adopted a novel approach to collect information on labour disputes in the B&R countries and to facilitate a qualitative analysis to test the practical implications of the doctrine of overriding mandatory labour rules.

Abstract

Purpose

The influence of road surface temperature (RST) on vehicles is becoming more and more obvious. Accurate predication of RST is distinctly meaningful. At present, however, the prediction accuracy of RST is not satisfied with physical methods or statistical learning methods. To find an effective prediction method, this paper selects five representative algorithms to predict the road surface temperature separately.

Design/methodology/approach

Multiple linear regressions, least absolute shrinkage and selection operator, random forest and gradient boosting regression tree (GBRT) and neural network are chosen to be representative predictors.

Findings

The experimental results show that for temperature data set of this experiment, the prediction effect of GBRT in the ensemble algorithm is the best compared with the other four algorithms.

Originality/value

This paper compares different kinds of machine learning algorithms, observes the road surface temperature data from different angles, and finds the most suitable prediction method.

Abstract

Purpose

Although self-sacrificial leadership and ethical leadership exhibit similarities in their moral dimensions, recent research suggests that self-sacrificial leadership may be linked to an increase in unethical behavior for the collective benefit of one’s group. Existing studies have demonstrated that ethical leadership can mitigate organizational cynicism. However, the potential misalignment between group interests and ethics associated with self-sacrificial leadership raises concerns about its potential to foster cynicism. This study investigates the mechanisms by which self-sacrificial leadership influences organizational cynicism.

Design/methodology/approach

Survey data from 493 organizational members across 9 Chinese companies were analyzed using multiple regression analysis, and bootstrapping was employed to confirm the mediating effects.

Findings

Self-sacrificial leadership was found to have an overall reducing effect on organizational cynicism, with distributive justice and ethical CSR perceptions as significant mediating factors.

Originality/value

This study sheds light on the unique characteristics of self-sacrificial leadership, highlighting the elements of sacrifice and loyalty that may result in unethical, self-centered behaviors, and explores its influence on organizational cynicism. By revealing that the recognition of augmented group interests can diminish cynicism among organizational members regardless of morality, this study contributes to broadening the theoretical perspective.

Abstract

Purpose

This empirical study of one of China's biggest take-out platforms during coronavirus disease 2019 (COVID-19) explores the legal rights and protections for gig workers' availability time.

Design/methodology/approach

The study uses a quantitative survey and interviews of take-out platform riders, investigating the intrinsic features of working time and availability time. Labour law professionals and scholars are interviewed to verify the findings.

Findings

The availability time of take-out platform riders is difficult to define under the current legal working-time framework. There is a need for a specific method to define availability time, considering the multiple factors in gig-take-out-sector work. One option is to apply working-time regulations to availability time but to use a proportionality test to preserve flexibility whilst the platform offers protection to the riders during that time.

Research limitations/implications

Pandemic-related travel restrictions limited the authors' study to one take-out platform in Beijing. Future studies should cover a wider geographical area and multiple take-out platforms.

Originality/value

The study uniquely evaluates the availability time of take-out platform riders to determine appropriate public policy and theoretical implications. It proposes a proportionality test regulating riders' availability. In particular, the workers being “at leisure” during availability time could mitigate the platform's liability for full remuneration or moderate the ceiling of working hours. The occupational health and safety of riders must be fully protected, as they are still “at the platform's disposal” at that time.

Abstract

Purpose

The purpose of this study is to firstly, find out does the relationship between finance, trade and income inequality provides matching evidence using the macro- and firm-level data? Secondly, whether a causal relationship from the firm-specific data can be established.

Design/methodology/approach

The authors employed a panel data fixed effect regression and two-stage least square (2sls) using key instruments. Their analysis is conducted based on a sub-sample analysis that emphasizes Latin America Region (LAR), Africa (AFR) and Asia by merging South Asia, East Asia and Pacific Regions (SEAR). These areas are characterized by an unequal society represented by a mounting gini index (Robilliard, 2020; De Rosa et al. 2020). Accordingly, the authors estimated a comparable model to unfold the impact of finance and trade. Besides, the authors exploited the interaction between their predictors with labor productivity and ownership structure to claim the difference between the results using the two data sets. The effort to establish a causal relationship from the combined firm-level data challenges the current literature that leans towards either macro or micro perspectives.

Findings

The result obtained from macro-level data shows that while financial development widens income inequality, the impact of trade on income inequality is negative. However, the estimation result from the combined firm-level data portrays that the proportion of investment financed by banks and trade widens income inequality. Given the contrasting result concerning trade, the authors test whether the firm-level evidence is causal following different identification strategies. The exercise shows that the correlation presented in the paper is causal. That challenges the current literature that falls short of providing firm-specific evidence.

Social implications

The authors adds to a growing body of literature on finance, trade and income inequality by paying due emphasis on firms from 2006 to 2020. The authors show the private sector development effect on income inequality by linking topics from the firm and country-level data.

Originality/value

The authors extend the macro-level discussion and contribute to the existing literature by offering firm-specific evidence on the relationship between finance, trade and income inequality.

Abstract

Purpose

Servitization has been used widely by manufacturing firms to secure strategic positions in industrial transformation. However, its impact on firms’ market power remains to be investigated, especially in developing countries. This study aims to investigate servitization’s impact on firms’ market power, along with the moderating roles of research and development (R&D) intensity and firm size.

Design/methodology/approach

Using the two-stage least squares with instrumental variables (2SLS-IV) method, the authors conduct an empirical analysis of servitization in China based on panel data for 1,797 publicly traded manufacturing firms during the period 2012–2018.

Findings

The findings show that servitization helps increase a firm’s market power. Furthermore, heterogeneity analysis suggests that embedded servitization increases a firm’s market power, whereas hybrid servitization reduces it. The findings also indicate that this effect varies depending on critical firm conditions. Servitization’s effect on firms’ market power increases with R&D intensity but decreases with manufacturer expansion.

Research limitations/implications

This study describes the positive effects of servitization on firms’ market power in response to calls for research that will adopt a comprehensive business performance perspective on the servitization field.

Practical implications

The findings provide guidance for what type of servitization manufacturing firms should choose and how it fits with their size and R&D capabilities.

Originality/value

This pioneering empirical study uses a large longitudinal data set and the 2SLS-IV method to examine the effects of embedded servitization and hybrid servitization on firms’ market power. The findings provide a new perspective on ongoing discussions of “desertification” and the “service paradox.”

Abstract

Purpose

The purpose of this paper is to investigate the institutions involved in providing experience to entrepreneurs in China and analyzed the types of experience they provide. Moreover, the abilities of related organizations to shape experience were analyzed.

Design/methodology/approach

By using a multiple case study method, this qualitative study examined various entrepreneurial experience providers (namely incubator, entrepreneurship training institution, franchise store, entrepreneurship training network, and family business experience transfer) to understand the experience types and their supplying competencies.

Findings

On the basis of the types of entrepreneurial experience and the criteria for entrepreneurial competency assessment, the study results showed that the primary providers in China are the Start Your Business (SYB) program, incubators, and family businesses. Furthermore, for-profit social training organizations provided less experience than did governmental or private ones. The five providers mainly provided “know-what” entrepreneurial experience. Among the providers, family businesses and SYB offered experience that was conducive to entrepreneurial learning.

Research limitations/implications

Entrepreneurs are the subjects of entrepreneurship education, while this study mainly focused on analyzing the experience supplying competencies. Thus, future studies should explore the required abilities that are developed during entrepreneurship for various learners.

Practical implications

This study interpreted how to achieve Chinese mass entrepreneurship and innovation strategy in the context of the low development of entrepreneurship higher education. To improve their competencies in providing experience, providers must focus on developing proper curricula, effective transfer methods and teacher resources, and incorporating entrepreneurship education.

Originality/value

On the basis of social learning theory and human capital theory, this study developed a set of criteria for the assessment of the ability of entrepreneurial experience providers. This study analyzed how related institutions enhanced entrepreneurial experience, thereby expanding the relevant learning channels and providing options for entrepreneurs to accumulate experience in China.

Abstract

Purpose

The purpose of this paper is to examine the actual legal effect of collective agreements by focusing on the litigation regarding the implementation of collective agreements in China where current literature on the topic is scarce.

Design/methodology/approach

This paper deploys both quantitative and qualitative methods to investigate the features of litigation regarding collective agreements. The judgments on collective agreement by people’s courts nationwide from 1 January 2014 to 31 December 2018 provide the primary empirical data. The intrinsic features of collective agreement disputes are investigated to delineate different sorts of theoretically presumed legal effect, namely contractual, normative and other (if any). A number of collective agreement templates and texts have been gathered and analysed to further explore the factors leading to collective agreement disputes. A dozen of labour law professionals, workers, scholars and trade union officials, were interviewed to verify the findings.

Findings

The number of collective agreement disputes is relatively small compared to the number of valid collective agreements or the volume of other labour disputes. This study found no litigation initiated by trade unions to claim a remedy against a violation of a collective agreement by an employer. However, a growing number of cases were filed by individual workers to complain about the terms and conditions of their individual employment agreements in contradiction to the existing collective agreement. These data do not mean that collective agreements lack problems or have no significance in action. A novel effect – a “substitution effect” – is evident in the existing labour litigations and relatively popular amongst employers, as they often refer to the collective agreement when a written individual agreement, as the mandatory document, is absent. The advent of substitution effect reflects a pragmatic view amongst Chinese labour law professionals, employers and workers.

Research limitations/implications

Due to the recent establishment of the online judgments database, this study has focused on collective agreement litigation in people’s courts from 2014 to 2018, which is representative of the national trend of such disputes and thus provides valuable insights. Future studies should cover a wider time span and extend to the collective agreement disputes subject to labour arbitration to provide a fuller picture of the challenges and potential solutions.

Practical implications

By understanding the legal effect of collective agreements in reality, the legislature, workers and employers can act accordingly to enhance or empower it. The insignificant volume of both contractual and normative claims on collective agreements indicates the pressing need to inject something concrete into both substantive rights and the implementation mechanisms of collective agreements. The existence of substitution claims illustrates the room for further implementation of written individual agreements to reduce the need to borrow from collective agreements to fill the void left by the absence of individual agreements.

Originality/value

This study uniquely evaluates collective agreement disputes in China to seek their true legal effect, finding the substitution effect of collective agreements that was absent from the prior literature. The features of collective agreements are reflected in this work, together with public policy and theoretical implications.
